Conservation agriculture for increasing maize yield in vulnerable production systems in central Mozambique
Smallholder farming under rainfed low input crop production in central Mozambique is characterised by decline in soil fertility, low yields and risks of crop failure. To revert this situation, conservation agriculture (CA) ...
The adaptive capacity of maize-based conservation agriculture systems to climate stress in tropical and subtropical environments : a meta-regression of yields
(Elsevier Masson, 2018)
Conservation agriculture is widely promoted across sub-Saharan Africa as a sustainable farming practice that enhances adaptive capacity to climate change. The interactions between climate stress, management, and soil are ...
Where to target conservation agriculture for african smallholders? How to overcome challenges associated with its implementation? experience from Eastern and Southern Africa
(MDPI AG,; MDPI, 2015)
Since the paper by Giller et al. (2009), the debate surrounding the suitability of conservation agriculture (CA) for African smallholders has remained polarized between proponents and opponents. The debate also gave rise ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
A short-term assessment of carbon dioxide fluxes under contrasting agricultural and soil management practices in Zimbabwe
(Canadian Center of Science and Education, 2015)
Two of the biggest problems facing humankind are feeding an exponentially growing human population and preventing the accumulation of atmospheric greenhouse gases and its climate change consequences. Refined agricultural ...
Short-term impacts of tillage and fertilizer treatments on soil and root borne nematodes and maize yield in a fine textured cambisol
(Society of Nematologists, 2018)
tc. Conservation agriculture (CA) based on the principles of minimum soil disturbance, crop residue retention, and crop rotation has been the focus of intensive research in recent years. A study was carried out to determine ...
Evidence and lessons learned from Long-Term On-Farm Research on Conservation Agriculture Systems in communities in Malawi and Zimbabwe
A long-term study was carried out in the Zidyana Extension Planning Area (EPA), Malawi and in the Zimuto Communal Area, Zimbabwe, to evaluate the effect of different conservation agriculture (CA) systems on crop productivity, ...
Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
(Cambridge University Press, 2012)
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Smallholder farmer innovation and contexts in maize-based Conservation Agriculture Systems in Central Malawi
(Canadian Center of Science and Education, 2017)
The increased threat of food insecurity and climate change requires more sustainable ways of agriculture intensification in African smallholder farming systems. Ample evidence confirms that maize-based conservation agriculture ...
Conservation agriculture for small holder rainfed farming: Opportunities and constraints of new mechanized seeding systems
Small holder farmers in rainfed agriculture believe that soil tillage is needed to maximize crop yields. However, as cropping intensity, and hence tillage intensity, increases there may be a decline in particular physical, ...
